  2. 2. The Duodenal Mucosal Bicarbonate Secretion Role of Melatonin in Neurohumoral Control and Cellular Signaling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Markus Sjöblom; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; alkaline secretion; central nervous system; duodenal enterocyte; duodenal ulcer; duodenum; enterochromaffin cell; human; intraarterial; intracellular calcium; intracerebroventricular; melatonin; rat; vagal nerve; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Sammanfattning : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. LÄS MER

  3. 3. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

    Detta är en avhandling från Göteborg

    Författare :Charlotte Von Bothmer; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

    Sammanfattning : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. LÄS MER

  4. 4. Pathogenesis and Diagnosis of Food Hypersensitivity in Adults

    Detta är en avhandling från Göteborg : Göteborgs Universitet

    Författare :Jenny Magnusson; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Birch pollen allergy; DBPCFC; Diagnosis; Duodenal mucosa; Eosinophils; Faecal samples; Food induced gastrointestinal hypersensitivity; IgE; Neutrophil MPO; T lymphocytes;

    Sammanfattning : Objective tools to diagnose local gastrointestinal (GI) inflammatory reactions in patients with food hypersensitivity are lacking. To fully appreciate the mechanisms mediating allergy-like reactions in the GI tract and for improvement of diagnostic techniques more knowledge is required. LÄS MER

  5. 5. On angiotensin II receptor type 2 receptors in the small intestine

    Detta är en avhandling från Göteborg

    Författare :Sara Ewert; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; renin-angiotensin; angiotensin; small intestine; mucosa; epithelium; AT1; AT2; bradykinin; BK2 receptor; nitric oxide; iNOS; smooth muscle; contractility;

    Sammanfattning : The endocrine renin-angiotensin system (RAS) is important in the regulation of extracellular fluid volume and systemic blood pressure in strenuous conditions such as hypovolemia. Also present locally in peripheral tissues, all components of RAS are expressed and have been shown to modulate development, cell growth and inflammation. LÄS MER
